[api] Address Copilot review on proxy benchmarks PR

Browse Source 
- Make UARTFlushResult in the serial_proxy stub a scoped enum class with
  matching scoped enumerator return in flush_port(), so the stub
  signature lines up with the real esphome::uart::UARTFlushResult.
- Replace heap-leaking lazy-init in get_ir_timings_100() with a
  function-local static const std::vector populated by a regular helper
  function. Same lazy-init behavior, no leak in valgrind/ASan, no lambda
  IIFE.
- Emit field 6 (modulation = 1) in build_infrared_rf_transmit_wire() so
  the bytes match the documented field list and the decode benchmark
  also exercises the field-6 decode_varint path.
